Proofing Systems

By | May 12, 2015

The purpose of the proof is to provide the customer, pre-press technician and printer with a means of having a common understanding of how the printed work should look.

This lesson will explore the different purposes and uses for a proof and will analyse the different types of proof, including the advantages and disadvantages of each proof. The lesson will also analyse the theory of how colour is produced on different systems, and the difference between viewing an image in a computer screen, where the colour is represented by adding light (additive colour theory) and viewing a printing or physical image, where the colour is seen by reflecting light (subtractive colour theory).

Read through the presentation then answer the questions below to test your knowledge. This lesson should take approximately 30 minutes, however you might want to take longer research some of the individual topics. You can revisit this lesson at any time.
